GASTON A. BRONDER, OF BROOKLYN, NEWV YORK.

GAS-RETORT-CHARGING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 765,809, dated July 26,1904.

Application filed June 28, 1902- .Serial No. 113,577- (NO model.)

Z0 all w/tom it may concern:

Be it known that I, GASTON A. BRONDER, a citizen of the United States,and a resident of the borough of Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inGas- Rctort-Charging Apparatus, of which the following is aspecification.

This invention relates to gas-retort-charging apparatus; and its objectis the production of means by which coal and the like can be fed intothe retorts of retort-stacks, so as to pile the coal in thick layers atthe sides of the retort and leave a channel through the coal on thebottom of the retort parallel to the longitudinal axis thereof. Theseobjects are obtained by applying my invention to the scoops of myretort-charging apparatus shown and described in my Patent No. 67 6,025,dated June 11, 1901, and in my patent application filed January 18,1902, Serial No. 90,306.

The specific improvement which forms the subject-matter of thisinvention is contained in a scoop and its appurtenances, comprising animproved plow and scrapers for the scoop, and by means thereof the coalis lifted as it leaves the scoop and is then directed to the sides ofthe retorts. The lifting of the coal allows it to slide down the sidesof the plow and pile up at the sides of the retorts.

Referring to the drawings, Figure 1 shows a plan view of the scoop withits scrapers and plow. Fig. 2 represents a side view of Fig. 1. Fig. 3is a partial section of Fig. 1 on the line :0 0, showing an end view ofthe plow, a swinging scraper, and an outline of a retort as viewed inthe direction shown by the arrow. Fig. 1 shows a section, on an enlargedscale, of the scraper shown in Fig. 3 on the line :0 m Fig. 5 representsa section of the scoop on the line :0 m of Fig. 1, with an end view ofthe scoop looking in a direction opposite to the arrow. Fig. 6 isapartial longitudinal section of Fig. 1 on the line 00* m. Fig. 7represents an elevation of one of the swinging or pivoted scrapers withits cover. Fig. 8 shows a partial section of Fig. 7 on the line 1'0 Fig.9 is an end view of Fig. 7. Fig. 10 represents an elevation of astationary scraper. Fig. 11 shows an end view of Fig. 10. Fig. 12represents a'section of the scoop on the line no a of Fig. 1. Fig. 13shows a perspective view of the ends of the scoop. Fig. 14 shows aperspective of a portion of the scraper-frame.

The scoop is shown at T and consists of a long box open at the top andat one end. The said box comprises the sides T and depressed bottom T Toa weight 1 in the rear portion of the scoop there is fulcrumed a lever Aby means of a pin a, and a backing-bar B is arranged to move through therear end T of the scoop.

Within the scoop and lying loosely upon the upper edges of the sides Tthereof there is a scraper-frame J, which comprises the side bars Jstops J and cross-braces J, to which latter are pivoted scrapers J Apulley G in the rear end of the scoop is connected by a chain M to apulley C on the backing-bar B. The said chain M is fastened to theweight I at in the scoop, leads over the pulley C, then runs over thepulley C, and is finally fastened to the weight I at iof thescraper-frame J, all of which parts are not new, being fully describedin my Patent No. 676,025 and my patent application filed January 18,1902, Serial No. 90,306.

Swinging scrapers, as already stated, are pivoted to. the cross-bracesJ, each comprising a blade J, (see Figs. 7, 8, 9, l2, and 14,) which isout out at its lower edge, as shown, on the line 6 t 16'', forming anotch in the blade. A door or cover V, with a triangular notch t", isflexibly connected to the said blade by chains w. A rear scraper J 3 isrigidly secured to the scraper-frame J, and forms the back coal-space inthe scoop. It is cut out on the line 2, t t, Figs. 10, 11, and 1 1, anda door or cover J with a triangular notch 25 is flexibly connected withthe scraper J 3 by means of chains Q0.

A plow N, the larger end of which extends considerably out of the bodyof the scoop, comprises sides 12., which with the bottom of the scoopconstitutes a frustum of a triangular pyramid. It is fastened to thebottom of the scoop by means of ears of, and its end v1. butts against atriangular projection M in the bottom of the scoop. The top and sides ofthe scoop are cut away, as shown at J In Figs. 3 and 4: a modified formof scraper is shown to comprise a blade J which is cut out on its loweredge on the line 25 t, forming a notch in the blade. From the said bladeJ there extend projections 6 that support a plate 25 to form aninclosure for a cover or door U, the latter having a triangular notch inits lower edge.

To operate and use my invention, the box T of the scoop is filled withcoal through its open'top, the scraper-frame J, with its appurtenances,being in position, as shown in Fig. 1. Then to empty the charge of coalthe scoop, with its scraper-frame and scrapers, is by any suitable meansmoved into a retort or the like to an extent a little greater than thatpart of the scoop which contains the said charge. Next the scoop iswithdrawn from the retort, the scraper-frame, with its scrapers, beingdetained therein by any suitable means. While the scoop is thuswithdrawn, while the scrapers remain stationary, the coal is dischargedi'rom the scoop, because the coal is held back by the scrapers andpushed off of the scoop as the latter passes under the scrapers. As thescoop is withdrawn the plow N thereon will raise the covers V and J",the chains w w allowing the scrapers to rise. As the plow passes throughthe coal held in the scoop the said coal is lifted and at the same timeforced to the sides of the retort. During the withdrawal of the scoopfrom the retort and while the scrapers are detained in the said retortthe backing-bar B is moved through the rear end T of the scoop. Afterthe scoop has into the scoop through the rear end T, by

which the scrapers, with theirappurtenances,

will be drawn into proper position in the scoop.

It will be noted that the chains w w, by which the doors or covers ofthe blades of the scrapers are held, allow the said doors or covers toswing over the plow as the scraperframe is moving into position on thescoop.

Having described my invention, I claim 1. In a scoop of aretort-charging apparatus, the combination of a scraper frame withscrapers arranged to slide on the scoop, covers arranged to rise, lowerand swing on the scrapers, a plow with rising and horizontallydivergingsides on the scoop, and arranged to pass under the scrapers.

2. In a scoop for a retort-charging apparatus, the combination of ascraper-frame with scrapers, covers on the scrapers, flexibleconnections between the scrapers and the covers.

3. In a scoop of a retort-charging apparatus, the combination of a.scraper frame with scrapers,notches in the scrapers,covers on thescrapers for the openings therein, chains connecting the scrapers andcovers.

Signed at New York, in the county of New York and State of New York,this 17th day of June, A. D. 1902.
